To all whom it may conce'mc' Be it known that we, DUDLEY CROWTHER and NED C. HARDY, citizens of the United States, residing at Great Falls, in the county of Cascade and State of Montana, have invented certain new and useful Improvements in TypeWVriting Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 'it appertains to make and use the same.

This invention relates to improvements in typewrlting machines and particularly to improvements 111 line indicating attachments therefor.

One object of the invention is to provide a line indicating attachment for typewriting machines whereby the position or line for starting the page of writing is indicated and whereby the approach of the end of cated so that all of the typewritten pages will be uniform and will contain the same number of lines.

Another object is to provide an attachafter the sheet is half filled, the number of lines that can be written before the end of the sheet is reached thus enabling the operator to determine with accuracy how much more matter can be written on the sheet,

invention consists'of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a front view of the platen roller and adjacent parts of a typewriter illustrating the application of the attachment, the latter being shown as indicating the position for inserting a. sheet of legal size paper; 2 is a similar view of one end of the roller and adjacent partsof-themachine showing the position of the attachment for indicating the placefor beginning the writing; Fig. 3 is a similar view showing the position of the attachmentmfter the first half vof'the page has been written and wherein the number ofZhnes which may be written on the lower portion of the page is indicated; Fig.4. is a similar view showing the pos tion of the attachment when the same indlcates that the bottom of the sheet has been reached and that the sheet should be of the attachments for each end of the roller laid-out fiat; Fig. 8 is a similar View of the reverse side of one of the attachments with parts broken away and in section; Fig. 9 is an enlarged longitudinal sectional view through one of the attachments taken on the line 99 of Fig. 7

Our improved line indicating attachment preferably comprises two members 1 and 2- one of which is arranged on each end of the platen roller. of the type-writing machine to which the attachment is applied. The members 1 and 2 may be constructed of anysuitable material but are preferably formed of thin sheet metal cut into strips of suitable width and of-a length sui'ficient to encircle the roller which is preferably reduced at its ends the thickness of the metal of which the members are constructedso that when said.

members are applied to the roller the outer surfaces thereof will be flush with the surfaces of the roller.

Arranged on the strips 1 and 2 adjacent to their outer edgesare series of numbers which are here shown as beginning with 7 atone end of the strips and as decreasing in value to the numeral 1 after which the word' spacing of the numerals for each make of machine to which the attachments are ap- 1 plied will be arranged to correspond with the spacing of the machine. It will be also understood that while 15 numerals are shown in the present instance that the strips may contain any number according to thenumber of lines the sheets or pages to be written on will contain. In the present instance the strips 1 and 2 are shown as arranged for use on the roller of an Underwood typewriting machine.

In addition to the numerals the strips 1 and 2 also have thereon certain designating lines and words which indicate the positions of the roller for inserting diiferent sizes or lengths of paper and for indicating the place where the writing on the sheets should begin. In the present instance the position for inserting a sheet of legal size paper is at the numeral 10 on the strips and this numeral is preferably of a different color from the other numerals and has on each side thereof a dash or line. Above the numeral 10 on the strips is placed the word Insert while below the numeral 10 is placed the word Legal. Between the numerals 13 and 14 on the strips is placed an arrow or a line above which is arranged the word Write and below which is arranged the word Legal. On each side of the numeral 4 on the strips are arranged lines or dashes. Above the numeral 4 on the strips is arranged the word Insert while below the numeral 4 is arranged the word Letter. Also on the strips between the numerals land 15 is arranged the word Out as hereinbefore mentioned, the word Out being spaced below the numerals 1 to a distance corresponding with the spaces between the numerals as shown. The words F Out are also preferably of a different color from the numerals. The various markings and words on the strips as herein shown and described are designed to indicate in conjunction with the scale bar of the machine the position for inserting legal and letter size sheets of paper, the position for beginning the writing on the sheets. and when the sheets are to be taken out or when the proper j number of lines, have been written thereon.

In Fig. 1 of the drawings the attachment is shown in position for indicating when a sheet of legal size paper is to be inserted in the machine which position, as hereinbefo-re stated, is indicated by the numeral 10 on the attachments, said numeral being difl'erentiated from the other numeralsin color as' well as having the lines and wording applied thereto in the manner described. In adjusting the attachment to this position the roller jacent to the scale bar which will indicate the proper position of the sheet for beginning the writing thereon. In thus adjusting the sheets the writing thereon will be started at the same place or on the same line in each sheet thus providing a uniform space or margin at the top of the typewritten pages. When adjusted in the manner described the typewritten lines will come between the numerals on the strips during the writing of the first half of the sheet and no attention need be paid to the indicating mechanism. After the first half of the sheet has been written the typewritten lines will come opposite to the numbers on the attachment which will indicate exactly how many more lines remain .or may be written on the remaining space or lower portion of the sheet, thus enabling the operator to ascertain with accuracy just how much more matter can be written on t-he sheet. For instance, assuming that line 12 is being written as shown in Fig. 3 of the drawings, the operator will know that there can be eleven more lines written on the sheet before the word Out appears above the scale bar as shown in Fig. 4 of the drawings and which indicates that the bottom of the page has been reached and that the sheet should be removed, after the page has been numbered, if the latter is desired.

In Fig. 5 of the drawings the attachment is shown as adjusted to bring the numeral 4 thereon above the scale bar of the roller,

said numeral having the designating marks ping or entering the machine unevenly and to prevent the roller from turning WltllOlll carrying the sheet therewith, the strips 1 and .2 are provided with paper gripping tongues 3 and 4 which are located adjacent to the inner edges of the strips and in approximately the same positions indicated in the drawings. In applying the tongues .4- to the strips the latter have formed therein at about the positions shown slots or elongated apertures 5 and 6, said slots or apertures' being twice the length of the tongues 3 and 4 which are respectively arranged therein and are hingedly connected at their inner ends to the strips midway between the ends of the slots as shown.

The tongues 3 and 4 may be hingedly attached to the strips in any suitable manner, said tongues, however, being here shown and are preferably hinged to the strips by short transversely disposed pintles or pivot rods 7 the ends of which are engaged with sockets 8 formed in the strips at diametrically opposite points midway between the ends of the slots 5 and 6. The inner ends of the tongues are hingedly fastened to the transverse pintles or pivot rods 7 preferably by turnin the ends of the tongues around said pintl ias or rods as shown. In thus hingedly attaching the tongues to the strips it will be seen that the tongues may be swung in. either direction toward the strips or into the opposite ends of the slots 5 and (i.

The tongues 3 when placed approximately in the positions indicated will be in the proper place to receive and grip the end of the paper when the roller has been turned to bring the numeral 10 on the attachment in line with thescale bar as shown in Fig. 1 so that the moment the platen roller is turned to feed the paper into the machine the tongues will immediately close against or grip the paper as said tongues and paper pass between the platen roller and the feed rollers of the machine thereby causing the paper to be positively moved with the platen roller and obviating any danger of the latter turning without the paper after the same has been properly applied thereto. In the same manner when the roller and the attachments thereon have been adjusted to the position for inserting letter paper the tongues 4 on the strips will be in position to receive and grip the ends of the sheet when inserted. By hingedly attaching the tongues 3 and 4 and arranging the slots 5- and 6 so that said tongues will spring in either direction it will be seen that if for any reason it should be desired while writing to turn the platen roller backward, the tongues will swing around in the properdirection to permit the same to readily pass between the platen roller and the feed rollers when turned or moved in this reverse direction thus obviating any danger of thev tongues forming obstructions or interfering in any way with the reverse movement of the platen roller and paper.

As hereinbefore stated the strips 1 and 9. may be of any suitable width to accommodate the row of numerals and the paper grin )in ton ues and said stri )s are. of such length that when engaged with the reduced ends of the platen roller the-ends of the strips will abut. The strips may be secured to the ends of the platen roller in any suitable manner and are here shown as being fastened by shortbrads driven through the strips and into the roller at suitable points; By providin an indicating strip at each end of the ro ler it will be seen that should the paper be of such width or placed in the machine in such position as to cover-the strip at one end of the roller, the strip at the opposite end thereof will indicate the positions and other information hereinbefore described.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

.Various changes in the form, proportion and the minor details of construction may be'resorted to withoutdeparting from the principle or sacrificing any of the advantages of the claimed invention.
